There isn't any overarching rule as to the right age for plastic surgery. In fact, the appropriateness of a certain procedure should be determined more on a case by case basis, looking at the individual's unique body type and aging process. Of course, there are age tendencies for certain procedures. Facelifts generally are not performed on patients under 30, as mini-lifts or laser procedures might be suggested instead, but this is not a rule. Otoplasty, on the other hand, is appropriate for adults or patients as young as 5 years old.
